INDUSTRIAL ADHESIVE PRODUCTS AVAILABLE FROM PERMABOND
Permabond manufactures various types of adhesives with different chemistries. This offers customers a greater choice of properties and benefits which can be matched to the requirements of the user.
ANAEROBIC ADHESIVES & SEALANTS
TYPICAL USES: Threadlocking nuts and bolts, pipesealing threaded pipe joints, form-in-place gaskets, retaining bearings and coaxial joints.
CHARACTERISTICS: Single part liquid - no mixing required. For use on close fitting metallic surfaces, maximum gap fill 0.5mm.
CURE MECHANISM: Presence of metal and absense of oxygen. Handling time is normally around 20 minutes (depending on the metal surface reactivity).
TYPICAL USES: Ideal for bonding plastics, rubber, metal and wood. Ideal for bonding small items and for high speed automated production lines.
CHARACTERISTICS: Single part liquid - no mixing required. Maximum gap fill 0.5mm. Not recommended for spreading over large areas.
CURE MECHANISM: Reacts with miniscule traces of moisture present on most surfaces, parts have to be held together tightly for the adhesive to cure (which is normally in a matter of seconds).
1-PART EPOXY ADHESIVES
TYPICAL USES: High strength structural bonding of metals, plastics and composites.
CHARACTERISTICS: Ultimate strength performance and environmental resistance.
CURE MECHANISM: Requires a heat cure (normally an oven between 100°C - 150°C) cure time is around 30 minutes.
TYPICAL USES: Bonding building materials, wood, metal, glass, plastics. General bonding and sealing applications.
CHARACTERISTICS: Single-part - no mixing required, low strength, flexible, can be used for gap filling.
CURE MECHANISM: Slow moisture cure (skins over first)
2-PART EPOXY ADHESIVES
TYPICAL USES: High strength structural bonding of metals, plastics and composites. Laminating, potting, coating and encapsulation.
CHARACTERISTICS: Generally available in twin pack cartridges or bulk. Range of viscosities and gap fill capabilities.
CURE MECHANISM: Requires thorough mixing of resin and hardener. Handling time varies from a few minutes to several hours. Cure can be accelerated by heating.
TYPICAL USES: High strength bonding of metals, plastics and composites.
CHARACTERISTICS: Available in twin pack cartridges. High peel strength, good impact resistance, good thermal resistance
CURE MECHANISM: Requires thorough mixing of resin and hardener. Pot life is fairly short (less than 10 minutes).
TYPICAL USES: High strength structural bonding of metals, magnets, ferrites, plastics and composites. Popular for motor magnet bonding.
CHARACTERISTICS: Rapid strength development, ideal for high speed production lines.
CURE MECHANISM: Single part, two part resin and brush on initiator, two part premix (in cartridges with nozzles) or bead-on-bead available. Fixture time ranges from seconds to minutes.
TYPICAL USES: Glass to metal bonding, furniture, decorative glass work, plastic bonding
CHARACTERISTICS: Most are colourless, clear and non-yellowing for an aesthetically pleasing bond.
CURE MECHANISM: UV-light exposure - cure in seconds on exposure to UV light.
