High Performance Sealant

Formoa® 063

Formoa 063 is a single-component MS Polymer adhesive sealant. It is designed for sealing and low-strength bonding applications that require a low viscosity and high grab sealant.

High grab

Reduced viscosity

Versatile all round sealing and bonding


290ml Cartridge

600ml Foil Pack


Formoa 063 is a versatile multi-purpose adhesive sealant, expertly formulated to have high grab and reduced viscosity. With proficiency in bonding a vast array of substrates, including metals, plastics, composites, and wood, it stands out due to its dual-purpose capability, performing equally well as a sealant and a semi-structural adhesive. A curing time of 8 hours ensures a strong, reliable bond, and its high safety profile only accentuates its appeal. However, users should be mindful of potential allergic reactions, though this is very rare.

Industrial Applications that are sealing and bonding:
Industrial manufacturers that require one product in their process which can bond as well as seal. This helps to avoid the number of products being used and keeps cost and misapplication errors to a minimum.
Interior and exterior sealing/bonding applications:
Any lightweight bonding or sealing application that needs a high-quality product to remain durable and not compromise performance. The excellent stay-white properties make help it retain the aesthetic benefits.

Key features

Good adhesive strength compared to other sealants
High flexibility
ISEGA food safety approval
High grab
Excellent ‘stay-white’ properties
Colour matching capabilities
No health risks

How to use

Application Temperature:
Between 1℃ and 30℃
(Lower temperatures will increase thickness)
Surface preparation:
Clean surface to remove grease and contamination. Then apply Formoa surface activator prior to bonding and allow 10 minutes to flash off. General sealing will not require the use of surface activator.
Method will depend on foil pack or cartridge use. If unsure on the correct method of application, follow your company's SOP or watch the 'How-To' video in the media section below.
Use an approved soapy solution before the skin over time.




Yes, once Formoa 063 is fully cured, it can be painted over. You can also colour-match the product to avoid the need for painting over. As there is no silicone based ingredients in Formoa 063, it will not cause paint bubbling or cracking.

Yes and no. Formoa 063 does not contain any silicone-based ingredients. Instead, it is an MS polymer-based product. However, it is the same as silicone in that you can use Formoa 063 instead of a silicone sealant. It has higher performance properties than a silicone. So if you want a cheap and cheerful product, it isn't for you.

We have extensively tested Formoa 063 in our accelerated weathering machine. It provided very strong results. Even when exposed to harsh conditions, Formoa 063 remained strong and didn't have significant colour change.

You will need to wait at least 4-6 hours before putting Formoa 063 into light operation. It will take up to 72 hours for Formoa 063 to fully cure. The max open time of 30 minutes will mean you have to put the materials in place before that time otherwise the bond may be compromised.

No, Formoa 063 isn't a structural adhesive. However, that doesn't mean you can't use it in structural applications. Due to its impressive strength performance, it is more than capable of bonding lightweight substrates in place or applications that have a large bonding area.
