LSE Laminating Resin is a general purpose resin for spray or hand lay-up. Use with fiberglass or woven cloth. Requires the addition of MEKP catalyst.
The LSE range is specifically designed for high performance Marine and Transport applications using hand lay-up and spray application. This resin has rapid glass fibre wetting properties, excellent sprayability and reduced tendency towards shrinkage problems such as pre-release, while giving fast cure performance and maintaining a relatively wide green time, low exotherm and low colour in thick sections. The LSE resin contains a combination of additives which improve the working environment during and after application by substantially reducing styrene evaporation, while providing excellent interlaminar adhesion characteristics after delayed lay-up. This resin contains ingredients which reduce styrene emission during the application and give the cured laminate a tack-free surface. Low styrene emission resins alone will not enable the user to comply with the recommended atmospheric styrene levels, but with appropriate ventilation, these resins may assist in reducing the level of styrene in the workshop to which workers are exposed.
When a laminate is built up in stages with intermediate curing, each operation should be finished with a normal resin/glass fibre ratio. Excellent interlaminar adhesion properties have been demonstrated with LSE Laminating resin, following delays between lay-ups of up to 7 days. However, since conditions vary from workshop to workshop, the intervals between successive laminating operations should not exceed 48 hours unless the surface is abraded,(to ensure optimum secondary bonding). Any areas with an excess of resin should be abraded in any case if further laminates are to be applied.
