Description

B820 series is formulated from an exclusive polyester resin, combined with halogenated additives, high-quality raw materials, and specialized agents that provide enhanced fire-resistant performance.

These polyester barrier coats help accelerate curing and demolding times, while reducing the risk of print-through, orange peel, and blistering on the gelcoat surface.

Product Characteristics:

  • High fire resistance
  • Significant reduction of print-through
  • Excellent flexibility and crack resistance
  • Low shrinkage
  • Improved gelcoat curing and surface finish quality

Primary Applications:

B820 series is recommended for applications requiring fire protection, such as:

  • Specialized vehicles (rail transportation, buses, etc.)
  • Infrastructure components
  • Composite parts exposed to fire-risk environments

Recommended Application Methods:

Spray-up

Description and Specifications

The advanced technology of the barrier coats developed by Gelco gives them the following properties:

Crack resistance

Crack resistance measures a material’s ability to withstand stress without cracking

Resistance to blistering

Blister resistance measures a material’s ability to remain smooth and intact without forming bubbles under heat or humidity

Fire resistance

Fire resistance measures a material’s ability to slow the spread of flames and limit damage in the event of a fire

Reduce orange peel effect

Orange peel reduction indicates that a material or coating has a smooth and uniform surface

Low shrinkage

Low shrinkage means that a material retains nearly its original volume during curing

Print-through reduction

Print-through reduction indicates that a material or composite minimizes the appearance of visible fiber patterns on the surface
