Instructions for use

1. Surfaces must be clean, dry and free of grease and dust.

2. Shake the cartridge before use and attach it to the gun (manual, pneumatic or electric).

3. Apply at a temperature of 10 – 40 °C, optimally 15 – 25 °C, avoiding air entrapment.

4. Smoothing Apply before the skinning time has elapsed using Sika Tooling Agent N.

5. Remove uncured material with Sika Remover-208; hardened material can be removed mechanically.

6. To clean tools and skin, use Sika Cleaner-350H and water—do not use solvents on skin.

Store in the original, closed container in a dry place at temperatures between +5 °C and +25 °C, away from UV radiation and frost.
