ATTSHIELD 47
Attshield 47 is a novolac epoxy vinyl ester resin that resists corrosion in a wide range of solvent, acidic, and slightly alkaline environments. This tough, high-strength resin is used to make fiberglass-reinforced laminates with high impact strength and resistance to a variety of mechanical stresses. This resin is ideal for filament winding and the production of products that require resistance to harsh environments and temperature changes. This resin has excellent wettability and curing properties as well.

- Note
Gel time was determined at 25°C with 0.5% cobalt 6% and 1% PMEK added to 100 resin.
- Safety
Store below 25°C in order to maintain optimum resin properties, and avoid exposure to direct sunlight.; Keep containers sealed to prevent moisture absorption or loss of monomer.; Do not add an accelerator (accelerator) to the catalyst (PMEK).; Do not add organic peroxides to hot diluent

- Application
FRP equipment (tank, scrubber, pipeline, pipes, etc.); Industrially structural FRP materials; facing materials; ATTSHIELD 47 resin is designed for use with methyl ethyl ketone peroxide (MEKP) as a catalyst (Butanox M-60, Promox P200 TX). It can also be used with benzoyl peroxide (BPO). ATTSHIELD 47 is an unaccelerated resin and requires a 6% cobalt octoate solution as an accelerator. ATTSHIELD 47 is extremely sensitive to the content of the accelerator. It is necessary to control the dosage of the accelerator in order to increase or decrease the gel time. During the curing process, ATTSHIELD 47 is sensitive to changes in ambient temperature. For best results, the use of less than 0.7% PMEK catalyst is not recommended. For good resin curing under normal environmental conditions, the accelerator level should be maintained at 0.5-1.0%, and the PMEK level at 0.7% - 1.2%. If a longer gel time is needed, it can be adjusted using a 10% solution of tert-butyl catechin (inhibitor). At an ambient temperature below 15℃, it is necessary, add additional dimethylaniline (may cause yellowing of the laminate).
