GS Polymers GSP 1552-2

its low-viscosity A and B components are easily mixed into a readily pourable material. Once cured, it forms a tough, flexible elastomer, which resists degradation from water and ultra-violet light. This system is ideal for many potting and encapsulating applications where optical clarity is desired, or where UV and weather resistance are needed.

100% reactive (Contains no solvents)
Optically-clear
Pourable
Hydrophobic
Resistant to foaming

SIDE-BY-SIDE (SBS) CARTRIDGE:
The recommended method to ensure an accurate mix ratio when dispensing material from a SBS tube through a static mixer nozzle is as follows:
1. Remove the nozzle tip-cap by twisting and pulling it off. Do not discard tip cap unless all the material in SBS tube is used. Save for reattachment to seal remaining material in the SBS tube.
2. Extrude enough material until there is an even flow of material from both openings. Discard this material extruded from the SBS tube.
3. Attach the mix static nozzle by twisting it on the nozzle tip. Extrude material until ~2-3 cm (~1 inch) of material has extruded. Discard this material extruded from the mixer.
4. Material can now be applied directly to the bonding surface.
5. When application is complete and there is still material remaining in the SBS tube, remove and discard the static mix nozzle.
6. Clean the tip-cap thoroughly to prevent cross contamination of the tip openings.
7. Attach tip-cap back onto the SBS tube.
TO MIX BY HAND:
Mix Ratio by Volume: 1 parts by volume GSP 1552-2 Part A to 1 part by volume GSP 1552-2 Part B. Mix Ratio by Weight: 100 parts by weight GSP 1552-2 Part A to 100 parts by weight GSP 1552-2 Part B.
Pot-Life: Do not mix more than can be applied in 10 minutes. Gel time is about 30 - 60 minutes but will vary depending on the mass mixed and the ambient temperature.
Proportion out components according to parts by weight or volume ratio into a non-reactive container (polyethylene, polypropylene, or metal de-rimmed can). Container should be about five times larger than the volume of the mixed material. Mix components very thoroughly, preferably with a metal spatula, scraping the sides and bottom of container to incorporate all material.
If working time allows, transfer material to a clean container without scraping sides or bottom before applying. Material should be used immediately.
