- Adhesion
Soudaseal FC has an excellent adhesion on almost all substrates. Soudaseal FC has been tested on the following surfaces: steel, AlMgSi1, brass, electrolytic galvanized steel, AlCuMg1, flame galvanized steel, AlMg3, steel ST1403 and Kynar 500. Plastics that were tested include: polystyrene, polycarbonate (Makrolon®), PVC, polyamide, glasfiber reinforced epoxy and polyester (GRP). While producing plastics very often releasing agents, processing aids and other protective agents (like protection foil) are used. These should be removed prior to bonding. For optimum adhesion the use of Surface Activator is recommended.
NOTICE: bonding plastics like PMMA (ie Plexi® glass) and polycarbonate (ie Makrolon® or Lexan®) in stress loaded applications can give rise to stress cracking and crazing in these substrates. The use of Soudaseal FC is not recommended in these applications. There is no adhesion on PE, PP, PTFE (Teflon®), silicones and bituminous substrates.
- Remarks
Pre-testing for adhesion is intended to eliminate potential problems. This testing will aid in determining the proper surface preparation method. May be painted, however due to the large number of paints and varnishes available we strongly suggest a compatibility test before application. The drying time of alkyd resin based paints may increase. Can be applied to a wide variety of substrates. Due to the fact that specific substrates such as plastics, like polycarbonate, etc. may differ from manufacturer to manufacturer, we recommend preliminary compatibility tests. Porous surfaces in water loaded applications should be primed with Primer 150. Lower temperatures and humidity will extend curing time. Contact with plasticizer containing plastics (e.g. flexible PVC, butyl rubber, EPDM,…) can lead to incompatibilities, such as discoloration or loss of adhesion. We recommend a preliminary compatibility test. We recommend a preliminary adhesion test on every surface.
Applications & Uses
- Applications
- Application Method
- Cure Method
- Applications
- can be used for mirror installations with additional mechanical support
- sealing and bonding in building and construction industry and metal working industry
- elastic bonding
- bonding applications in the automotive industry (cars, coaches, caravans, trains)

- Direction for use
Substrates
Surface Preparation: clean, dry, free of dust and grease
- It is expected that the product will adhere and perform in uncontaminated joints with most common construction substrates, without the use of a primer.
- Porous surfaces in water loaded applications should be primed with Primer 150.
- Surface Activator may be used to pretreat nonporous surfaces.
- We always recommend preliminary compatibility tests pervious to application.
Resistance to chemical agents:
Good resistance to water, aliphatic solvents, mineral oils, grease, diluted inorganic acids and alkalis. Poor resistance to aromatic solvents, concentrated acids, chlorinated hydrocarbons.Joint dimensions:
- Minimal Width: 1/4”
- Maximum Width: 1 3/16”
- Minimum Depth: 1/5”
- Recommendation: width = 2 x depth
Bonding Layer:
We recommend a bonding layer of at least 5/64” to achieve a bond with maximum elastic properties.Application:
- Method: Manual- or pneumatic caulking gun.
- Application temperature: -35°F to +140°F.
- Cleaning: with IPA immediately after use and
- before curing. Repair with: Soudaseal FC.

Safety & Health
- Health and Safety Recommendation
KEEP OUT OF REACH OF CHILDREN. Avoid skin and eye contact. On contact, uncured sealant could cause irritation to skin and eyes. In case of eye contact, flush eyes with warm water for 15 minutes, call a physician. For skin contact, remove sealant with a paper towel. If swallowed, do not induce vomiting, call a physician. Soudaseal FC is manufactured for professional use only. Refer to Material Safety Data Sheet (MSDS) for further information.
