Applications & Uses
- Markets
- Application Area
- Applications
- Can be used for mirror installations as a 1 step product.
- Sealing and bonding in building and construction industry and metal working industry.
- Sanitary and kitchen areas, resists mold growth.
- Structural elastic bonding.
- Structural bonding applications in the automotive industry (cars, coaches, caravans, marine, trains).
- Elastic bonding of panels, profiles and other pieces on the most common substrates.
- Adhesion
SoudaSeal FC has an excellent adhesion on almost all substrates. SoudaSeal FC has been tested on the following metal surfaces: steel, AlMgSi1, brass, electrolytic galvanized steel, AlCuMg1, flame galvanized steel, AlMg3 and steel ST1403. 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. Bonding plastics like 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®) and PMMA (ie Plexi® glass).
- Substrates
- Type - all usual building surfaces, most metals, polyesters and many plastics.
- Not suitable for PE, PP, PTFE (Teflon®), ABS or PMMA (ie Plexi® glass).
- 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 non-porous surfaces.
- 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.
- Limitations
- Pre-testing for adhesion is intended to eliminate potential filed 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.
- Product Application
- Method - Manual- or pneumatic caulking gun
- Application temperature: 34°F - 90°F
- Cleaning - With IPA immediately after use and before curing.
- Repair - With SoudaSeal FC
- A bonding layer of at least ¾” to achieve a bond with maximum elastic properties.
