Is MS polymer better than silicone sealant?

MS polymer sealants are generally better than silicone sealants for applications that require higher quality, greater adhesive properties, and better mold resistance. However, silicone sealants are cheaper, easier to work with, and have a higher temperature resistance.

Here are some ways MS polymer and silicone sealants compare:
Strength: MS polymers are stronger than silicone sealants and can achieve higher strengths without a primer.

Weathering: MS polymers are UV resistant and perform well in weathering conditions.

Paintability: MS polymers can be painted in most applications, while silicone sealants typically cannot.

Temperature resistance: Silicone sealants have a higher temperature resistance than MS polymers.

Ease of use: Silicone sealants are easier to work with than MS polymers, which are usually thick and can be difficult to gun out.

Cost: Silicone sealants are cheaper than MS polymers.

Odor: Silicone sealants have a strong odor, while MS polymers are odorless.

Cure time: MS polymers cure faster than silicone sealants.

Tolerance: Silicone sealants are more tolerant than MS polymers, making it easier to remove and replace if you make a mistake.

MS polymers are a type of hybrid polymer sealant that combine the weathering performance of silicones with the strong performance of polyurethanes.
