Product Description

Surface Preparation

Crestomer 1186PA has excellent adhesion to FRP material provided that the surface has been maintained free of dust and grease. This can be guaranteed by the use of proprietary strippable cloths such as peel ply (without lubricant contaminates). If the laminate surfaces are more than 3 days old, it is recommended that they are lightly abraded and wiped with acetone or styrene on a lint-free, clean cloth prior to bonding.


Crestomer 1186PA is supplied pre-accelerated. The required hardener is Butanox M50 (or other equivalent MEKP catalyst). The catalyst is added at 2% w/v. Once the catalyst is incorporated, the colour will begin to change from blue to pale grey. Crestomer 1186PA can be applied with a spatula or from a dispensing unit, taking care to keep air entrapment to a minimum. A time lapse of 1 hour from gelation should be allowed between layers. Application should always be carried out at temperatures above 15?C. Recommended temperature range for application is between 18?C and 25?C.

The use of additional pigments or fillers is not recommended as they can affect the performance of the adhesive.

For industrial/commercial use only. The user must determine the suitability of a selected adhesive for a given substrate and application.
