- Storage
Polyester resin H 834 is stable for six months from the date of manufacture, if any stored in original containers stored out of direct sunlight at a temperature of no higher than 21 ° C. If the storage time and storage conditions are exceeded, a gel may form. During the hot summer months, the stability of the resin is predicted at 30 ° C for about 2 months. Consistent storage conditions help maintain gelation times and viscosity.
- Features
Excellent hydrolytic stability, ie resistance to water. It is characterized by good mechanical properties and excellent ability to permeate the fabric or mat. Contains at least 67% non-volatile substances. It is possible to achieve values significantly lower than required by the existing or proposed legislation. This reduction in styrene emissions is achieved without any reduction interlaminar (interlayer) adhesion.
- Additives
Some pigments, fuels or the addition of styrene can adversely affect the spray and the final properties of the H834 resin. Therefore, before any widespread use, these should the ingredients should be assessed.
- PACKAGING
Polyester resin H 834 is supplied in packages of 220 kg barrels and at the customer's request spills.
- Advantages
It is characterized by the following advantages. Fast lamination curing, allows to increase production speed without loss of surface properties due to shrinkage. Allows you to reduce the time normally needed for additional post tempering. Because it allows faster mold turnover, it is saving on the number of molds. It ensures a good relationship with osmosis and reduced blistering. It is characterized by good physical properties Approved by the Lloyd's Register.
