There are the powder and liquid resin for bonded abrasives production to meet the demand of different domain. This series is adopted advanced production equipment and processing. With strict formula design, effective molecular weight and distributing control method, it makes the distributing of resin molecular reach an extremely ideal status. The powder resin is characterized in strong viscosity, mechanical strength, abrasion resistance, heat resistance and wet grinding stability. As the excellent wetter, the liquid resin has a good wetting function and well-distributed miscibility. It makes the liquid resin with good humidity by the special processing. There is no caking under the high humid environment and with high intensity and good grindability, which is the excellent product for grinding wheel.
RytoR-4
RytoR-4 and R-4-02 40% glass fiber reinforced polyphenylene sulfide compounds provide a good combination of mechanical and electrical properties with outstanding chemical resistance, even at elevated temperatures.
This series of products is a solvent free aqueous dispersion based on terpene phenolic resin, mainly used as a tackifier, designed specifically to tackify a wide range of acrylic, SBR and other water based synthetic or natural polymer.    Â
Applications Â
-Pressure sensitive adhesives, contact adhesives and water-based industrial adhesives.
-A wide range of acrylic, SBR and other synthetic or natural polymer adhesives. Â
Properties:
-Solvent free
-High adhesion, high shear and good mechanical stability,
Terpene phenolic resin is a phenolic modified resin that increases polarity.It can improve the specific adhesion, hot tack or
flexibility of hot melt or solvent based adhesives.
Applications:
- EVA based hot melt adhesives for packaging, bookbinding, woodworking and labeling.
- SIS and SBS based hot melt pressure sensitive adhesives.
- Sealants based on butyl rubber or polyurethane.
- Solvent based adhesives formulated with acrylics or natural rubber.
-Rubber compounding, Tires,
Properties
1) Stronger tackifying than other resins.
2) Excellent heat resistance and stable color,
3) Wide compatibility, able to mix with many high polymer resins in a wide range, soluble in many polar or non-polar solvents.
Solubility:
Soluble in:
1) aromatic / aliphatic solvents like hexane & toluene.
2) Esters and ketones like ethylacetate and acetone.
3) Longer chain alcohols like propanol, pentanol, butanol.
4) Insoluble in water and ethanol.
Compatibility
compatible with ethylene, butyl acrylate copolymers, natural rubbers and synthetic rubbers (SIS, SBS, SBR, chloroprene, butyl), polyesters and acrylics. Also compatible with various resins (rosin derivatives, polyterpene resins, hydrocarbon resins) with waxes.
