Bonding agent / CG-O174

Artificial stone is a composite product based on unsaturated polyester resins and minerals. Silanes provide the chemical bond between the organic resin and the inorganic mineral. This also significantly increases the mechanical strength. 1 – 3 % are sufficient to significantly increase the strength.

Advantages:

  • Chemical bond between resin and fillers
  • Improved mechanical properties
  • Higher flexural strength

Why amides have no place in your compound

Erucamides are traditionally used to improve scratch and abrasion resistance. From time to time the fabric migrates to the surface, which leads to milky stains. When in direct contact with amides, they have a harmful effect on health. Furthermore, amides only offer short-term scratch resistance.

Our solution: We offer high molecular weight silicone-based masterbatches which significantly increase the scratch and abrasion resistance of the polymer and improve the mechanical properties of the extruded/moulded product.

SI-03B is a specially formulated masterbatch for HFFR compounds containing high molecular weight polydimethylsiloxane dispersed in polyolefin. SI-03B is used as an additive in polyethylene compatible systems.

Advantages:

  • Low coefficient of friction (CoF)
  • High surface gloss on extruded material
  • High abrasion resistance, like HDPE pipes/cables
  • Improved lubricity
  • Efficient demoulding
  • Higher production output

Innovative siloxane for HFFR compounds

Our “CG-VO10” is an innovative “silane-modified siloxane” whose polymer chain consists of vinyl, silica and ethoxy groups, among others. CG-VO10 is excellently suitable as a compatibility additive of organic polymers (PE, EVA, EPDM, etc.) with hydrophobic inorganic fillers (MDH, ATH, etc.).
In the presence of moisture the ethoxy groups of CG-VO10 hydrolyse to ethanol and reactive silanol groups. These silanol groups react with the filler via silicon-oxygen bridges. The vinyl functional groups of CG-VO10 can react with the polymer phase in the presence of radicals:
One main application for mineral-filled compounds is the cable industry. EPDM and EVA can be processed into highly filled cable compounds due to the adhesion-promoting and hydrophobising effect of CG-VO10.

CG-VO10 is highly suitable for EPDM and EVA polymers for halogen-free, non-toxic, environmentally friendly, flame-retardant cable compounds (HFFR) based on ATH and MDH.
The silicic acid incorporated in CG-VO10 reduces the amount of oxygen in the polymer, resulting in a significantly improved oxygen index.

Advantages:

The unique polymer structure of CG-VO10 compared to conventional mono- and oligomeric vinyl silanes is characterized as follows:

  • Innovative combination “flame retardancy” & low vapor pressure
  • Significantly improved limiting oxygen index (LOI) of 2-3 precentage points compared to oligomeric vinyl silanes in HFFR cables
  • Excellent dispersibility in fillers
  • Uniform surface wetting
  • “No-hazardous material” and still chemically reactive for a firm bond with the mineral filler

Perfect dispersion of any mineral filler with titanates/zirconates

The addition of only 0.2-0.4% shows amazing effects:

  • The filler content can be increased up to 70%, while the viscosity remains below 20’000 cps. The end products remain very flexible.
  • The mechanical properties improve significantly (e.g. +50% elongation at break) because the titanate/zirconate monolayer acts as an efficient adhesion promoter.
  • When using coordinated titanates/zirconates, your compound shows increased flame resistance due to phosphorous intumescence.
Titanate / Zirkonate bilden auf Füllstoffen eine monomolekulare Schicht und ermöglichen eine perfekte Dispergierung in der Polymerphase

Advantages:

  • Higher filler load and viscosity reduction: Titanates/Zirconates significantly reduce the viscosity of mineral-filled compounds and allow your compound to be loaded with fillers up to 70-75%.
  • As high-performance adhesion promoters, titanates/zirconates significantly improve the mechanical properties of filled polymers.
  • Flame retardancy through nano titanium phosphorous intumescence. Nano-phosphating to control the combustion rate. Nano-phosphating to control the combustion rate.
  • Lower extrusion temperatures for reactive compounding shear (torque x time) and up to 40% faster extrusion.

With Trigonox 101 cross-linked HDPE pipes for potable water certification

Peroxide initiators are not regulated at EU level. They are regulated by every single country. One European reference for the peroxide components is the German BgW. Section XLVI, which allows these ingredients for food contact applications in X-linked PE, with the restriction that the total amount of decomposition products in the final resin/product does not exceed 0.2%.
The included catalyst is allowed according to the German KTW recommendation 1.3.17 if the migration of Sn in potable water is below 5 microgram Sn/dm2. The maximum concentration of Sn in PE should be <0.08%.<

Trigonox 101 can meet the requirements of the BgW if the initiator is used correctly in HDPE PEX-b cross-linking and the dosage of the initiator is optimal.

Advantages:

  • Fifty-year service lifetime of the continuous and intermittent hot water line.
  • Maximum operating temperature of 110°C
  • Chemical resistance to solvents and oil
  • Creep properties and creep rupture resistance
  • Abrasion resistance
  • Impact resistance to resist crack propagation, especially at low temperatures
  • Resistance to slow crack growth

Note: The use of Trigonox 101 for products with potable water certification must be checked with the national approval authority in each case.

The adhesion promoter in rubber conveyor belts & tyres

The main use of resorcinol and resorcinol resins is as a bonding agent between the fabric inserts or steel cord with the rubber compounds. Resorcinol formaldehyde resins (phenol-resorcinol-formaldehyde adhesives) are used as adhesives in the manufacture of plywood and other wood structures. More recent applications are phosphoric ester-based flame retardants and lightfast transparent polymers.

Colour Masterbatches for Plastics

With our colour masterbatches, you benefit from the simplest processability, distinct colour strength and perfect dispersion in your plastic products or compounds.

Are you tired of using dust-dry powder pigments and tediously dispersing them?

Do you want to achieve your high-quality plastic product in as few steps as possible?

Read on and convince yourself of our colour masterbatches for the plastics industry!

Generally, powdered pigments have agglomerates that cannot be further broken down into primary particles by grinding processes or milling. This problem is mainly observed with the pigments phthalocyanine blue, phthalocyanine green, red, yellow and others.

In conventional masterbatches, this problem exists as such with only minor improvements. These agglomerates lead to so-called “specs” (poor dispersion due to non-dispersed particles) in blown films, thin injection-moulded parts and other thin plastic parts.

In our mono-colour masterbatches, the pigment is dispersed to the finest possible particle size by the use of special dispersing agents and additives by following strict process conditions.

These mono-colour masterbatches provide excellent dispersion in end-use applications and are available in red, yellow, blue, green, violet, and orange.

Food contact approved products are available for each colour.

Our colour masterbatches are highly suitable for the following applications:

  • Films (single and multi-layer)
  • Blow moulded parts
  • PP fibres
  • Injection moulded parts (especially thin-walled parts)
  • Compounds

The following advantages set you apart from your competitors:

  • Consistent colour strength
  • Excellent and uniform dispersion
  • Economic efficiency
