Abstract：
SCA-R74M is an organofunctional silane used to improve the physical and electrical properties of glass reinforced and mineral filled thermoset resin, typically those curing via a free-radical mechanism (e.g. polyester, polyurethanes and acrylics) and in filled or reinforced thermoplastic polymers, including polyolefins and thermoplastic polyurethanes.
Applications and Performance：
1. Significantly improves composite strengths when the composite is reinforced with fiber glass roving sized with a typical polyester compatible formulation. These formulations normally incorporate silane coupling agents, film-forming resins, lubricants and antistatic agents.
2. Enhances the strength performance both initially and after wet-conditioning, of cured polyester resin composites filled with silica, glass fiber, silicates and many metal oxides.
3. Enhances the wet electrical properties of many mineral-filled composites, such as crosslinked polyethylene and polyvinyl chloride.
Packing：
The regular packing of this product is 25kg plastic pail, 200L steel drums and 1000L immediate bulk container.
Storage and Shelf Life：
Should be stored in dry, cool, ventilated room; keep away from water, moisture, high temperature and fire. This product has a shelf life of at least 12 months if stored in tightly closed original container at room temperature.
If this product is kept beyond the shelf life recommend on the product label, it is not necessarily unusable, but a quality control should be performed on the properties relevant to the application.
