SIOResin Introduces Water-based Intumescent Fireproof Resin for Wood Coatings

SIOResin® WRS-1002 is engineered to provide exceptional flame resistance and thermal insulation. When exposed to heat, the resin rapidly carbonizes and expands, forming a thick insulation layer that effectively blocks oxygen and heat from reaching the substrate. This intumescent reaction is the key to its superior fireproof performance, allowing coated surfaces to withstand extreme temperatures and delay combustion.

With an expansion rate exceeding 100 times, SIOResin® WRS-1002 ensures comprehensive fire protection while maintaining a clear and smooth surface finish. Unlike traditional fireproof coatings, which often compromise aesthetics, this advanced resin allows for decorative transparency, making it ideal for wood coatings where natural grain visibility is desired.

Resin Features

A major advantage of SIOResin® WRS-1002 is its simple and adaptable formulation, making it highly accessible for coating manufacturers looking to develop fire-retardant paints with minimal adjustments. The resin features:

• Room temperature curing for convenient application
• Low viscosity with high solid content, ensuring smooth blending and application
• Excellent compatibility with common coating additives and binders

Expansion-type Transparent Coating Primer

To assist manufacturers in formulating expansion-type transparent fireproof coatings, SIOResin provides the following recommended starting formula:

Ingredient	Ratio (%)
Resin (WRS-1002)	100
Defoamer (Degussa 2290)	0.1
Wetting Agent (Dego 245)	0.1
Thixotropic Agent	Appropriate amount
Water, Alcohol, or Mixture	Appropriate amount

Formulation Process

• Add SIOResin® WRS-1002 to the mixing container and start stirring.
• Gradually introduce additives (defoamer, wetting agent) while maintaining medium stirring speed for 15 minutes.
• Check for shrinkage holes using a scraper; continue stirring if necessary.
• Adjust viscosity by adding water or alcohol, ensuring uniform distribution.
• Filter and package the final product for application.

Eco-friendly and Safe for Indoor Use

As a pure water-based resin, SIOResin® WRS-1002 meets strict indoor environmental standards, with formaldehyde emissions below 0.1 mg/m³, making it a safe choice for residential and commercial applications. Free from harmful solvents and VOCs, it aligns with sustainable manufacturing practices while ensuring top-tier fire protection.

'We are thrilled to introduce WRS-1002, a breakthrough in intumescent resin technology,' said Mr. Zhang, CEO of SIOResin. 'Its ability to expand over 100 times, maintain crystal-clear transparency, and comply with eco-friendly regulations makes it an exceptional choice for coating manufacturers looking to innovate in wood fireproof solutions.'

SIOResin® WRS-1002 is available in 200KG packaging and offers a shelf life of 12 months when stored under appropriate conditions.
