Outstanding adhesion to most common construction substrates, reacting with atmospheric moisture to form a durable and flexible seal with a high modulus of elasticity.

CPX33 HMA AQUARIUM silicone sealant offers excellent resistance to climatic ageing. 

CPX33 bonds strongly to clean uncoated glass, ceramics and glazed or painted surfaces, without the need to prime. For most other substrates it is recommended that a primer be used.

Specifically developed for construction applications, CPX33 is ideal for sealing applications where joint load is high and extended exposure to immersion is required.

Typical applications include; aquariums, fish tanks, fish ponds, water features water supply and drainage piping, swimming pools, spas, boats.
