ENTROPY CLX slow hardener for BRT/CLR resin (2.15kg)

105,16 € Tax included

BRT is a general purpose, clear, optical gloss and UV resistant laminating resin for laminating white surfboards and for hot coating. Based on the entropic CLR - Clear Epoxy Resin, BRT can be combined with all CLR Clear hardeners. BRT is a USDA BioPreferred® certified product with a 30% biobase content.

Usage: white surfboards, standing paddle boards

Consumption: approx. 3 litres for 1 short board of 2 m and approx. 12 litres for 1 SUP or 2 long boards

Working temperature: optimal temperature from 21°C to 30°C

Working environment: Prefer low-humidity environments, especially for use outside the optimal temperature range for the product.

Application tips :

  • For best results, mix the two components according to weight
  • Always mix the product thoroughly for at least 2 minutes, scraping all surfaces of the container to ensure thorough mixing.
  • It is preferable to use the product in a temperature-controlled environment within the optimal use limits of the product. Avoid cold ambient temperatures or high humidity.
  • For optimum curing performance, ensure that surfaces are dry and free of all dirt, debris and/or oil. Surface preparation by mechanical sanding is strongly recommended.
  • Perform pre-tests with the materials and processes being considered to fully understand the curing characteristics of the resin in your work environment and the compatibility of the resin with other materials.
  • Avoid using BRT on dark coloured surfaces as the optical brightener may degrade the appearance!
