Water-based mould release, MoldWiz®WB-2700, for epoxy spars

Axel Plastics Research Laboratories announced the success of a new waterbased
release, MoldWiz® WB-2700, in the production of epoxy spars for the marine industry. The
new release product is a silicone free emulsion of fatty acids, polyolefins, and surfactants in a water vehicle. The product contains no hazardous materials making it friendly to both the user and the environment. MoldWiz® WB-2700 is 10% active. 

A case history in marine spar production
A manufacturer produces epoxy spars for the marine market, wet wrapping, and then braiding carbon and Kevlar® tapes on 40’(12.1m) aluminum mandrels. Prior to evaluating MoldWiz® WB-2700, two different types of mould release, one fluoropolymer-based, the other, a silicone/alcohol mixture were employed to achieve good release. Neither mould release product by itself was judged adequate. 

MoldWiz®2700 was introduced to the process by simply spraying the 100% waterbased
release onto a clean mandrel using a hand pumped spray bottle, and then
lightly wiping the surface with a cotton cloth to ensure thorough coverage. The
mandrel was initially prepared with 3 coats of release before being introduced to
production.

The spars that employed MoldWiz® WB-2700 released easily with the single
release product. Plant workers were pleased with the elimination of the odor from
the alcohol/silicone based release and the manufacturer was pleased to eliminate
silicone (a possible contaminant) from the process area. 

MoldWiz WB-2700 is just one of the hundreds of products produced by Axel, a 67 year
old, ISO 9001 registered, manufacturer of proprietary mould releases and process aid
additives. All of Axel's products are formulated from raw materials that comply with the
