Applications 

1. Sizing Binder For Glass Roving And Reinforced Composites: Used as a glass roving size binder and coupling agent in glass reinforced thermosets and thermoplastics, it improves both the dry strength and the wet strength of the cured composite and helps the laminate hold its properties after moisture exposure.

2. Epoxy Encapsulants And Electronic Packaging: Added to epoxy based encapsulate and packaging materials, where it enhances the wet electrical properties, so that the cured resin keeps its insulating performance rather than losing dielectric quality once moisture reaches the interface.

3. Primer Free Sealants And Waterborne Adhesion: As an adhesion promoting additive it removes the need for a separate primer in polysulfide and urethane sealants, and it is particularly useful in waterborne systems where it improves the adhesion of acrylic latex sealants and of urethane and epoxy coatings.

4. Unsaturated Polyester And Filled Resin Systems: Used in unsaturated polyester composites and in mineral filled thermosets and thermoplastics, improving mechanical properties, electrical properties and light transmission, and lifting performance noticeably under wet service conditions.

5. Wire And Cable Insulation Compounds: Used to treat clay filled EPDM systems that are crosslinked by peroxide in the wire and cable industry, where it improves the dissipation factor and the overall dielectric behaviour of the compound.

 Quality Assurance 

Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.

Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
