HYPERSEAL-2K-F Two Component, Pourable Grade Polyurethane Sealant
تماس بگیرید
HYPERSEAL-2K-F is a two component, horizontal grade polyurethane sealant ideal for large construction joints. Upon curing it produces a high performance sealant that also provides significant waterproofing, with excellent resistance to various climatic and temperature conditions. Furthermore, the sealant has very good resistance to chemicals and other severe exposures.
The product complies with:
- ASTM C920
- DIN 18540
- SS-S-200D
- SS-S-200E, Type H (slow curing, hand mixing)

FEATURES & BENEFITS
- Excellent resistance to ageing, microorganisms, fungi and several chemicals
- Suitable for potable water (certificate available upon request).
- Oven paint-able
- Remains elastic even below -40oC
- Resistant to both salt water and sweet water
- Good resistance to microorganisms and a variety of chemicals
- Good mechanical properties
- Resistant to accidental contact with petroleum derivatives according to specification SS-S-200E
- Special Primers available for almost any substrate
APPLICATION
Recommended application temperature range varies between +5 oC to +25 oC. At higher temperatures, there is a decrease in the pot life of the material. Ensure that the joint to be filled is thoroughly cleaned and dried prior to application of the sealant. If the bottom of the joint is open, a polyethylene backing rod (or polystyrene) is inserted so as to leave a depth about half of that is the width of the joint. Apply a suitable primer depending on the condition of the substrate as well as the climatic conditions at the time of application.
- On porous substrate, use PRIMER-PU
- On humid substrates, use AQUADUR or UNIVERSAL PRIMER-2K 4060
HYPERSEAL-2KF A &B are thoroughly mixed and the final product is poured slowly into the joint. Alternatively the sealant may be applied by spatula or appropriate dispensing gun.
PRECAUTIONS
- No problem after fully cured.
- Ask for MSDS (Material Safety Data Sheet)
