Anaerobic

Description

Anaerobic are acrylic based adhesives which when applied on metal-surface close-fits and upon isolation from air, cure to form a bond.

Applications

The unique property of anaerobic curing make it suitable for closely-fitting metal parts and machinery parts such as thread locking, thread sealing, pipe sealing, bearing retaining, flange sealing etc. Notable applications include, thread locking in railway track nut & bolt joints, bearings in motors, engine gaskets for both petrol and diesel engines.

Curing Mechanism

In presence of metal and in the absence of air (particularly oxygen), polymerisation is initiated and a strong bond is formed.

Epoxy

Definition

Epoxy adhesive are regarded as the strongest adhesive available and have wide industrial use as structural (load bearing) adhesives. These are thermosetting adhesives, which solidify through chemical reactions. These chemical reactions take place either at room temperature or at elevated temperatures. These chemically reacted and solidified epoxy materials will only soften but do not melt on heating.

Applications

Bonding, gap filing, Potting and encapsulation.

Curing Mechanism

At the time of applying the epoxy adhesive on to the metal/plastic substrates, it is in the liquid state. This liquid adhesive thoroughly wets the substrate and thereby makes initiate contact with the substrates. During chemical reaction the liquid material gets converted into a solid material with negligible shrinkage. Once the liquid material is solidified, the cohesive strength increases. This results in forming strong bonding with the substrates.

Product types

  1. One component epoxy adhesive system: It contains an epoxy resin & a latent curing agent. Latent curing agents are inactive at room temperature and active at high temperature. When one component epoxy adhesive system is heated to high temperature, the chemical reaction between the resin and the hardener starts and the material gets cured in to a tough mass exhibiting high bonding strength.
  2. Two component epoxy adhesive system: These are room temperature curing systems. Epoxy resin and the hardener are packed separately and supplied as a package to the customer. These two are mixed in particular ratios (Weight or volume basis) during use. The mixed adhesive system is used within the potlife period to achieve optimum bonding strength. The complete curing of two part epoxy adhesive systems require a minimum of 5 – 7 days.

Polysulphide

Definition

In general elastomeric polysulphide Sealant is used for concrete expansion Joints applications. It is non-hazardous in normal use. Polysulphide polymer results from the polycondensation of bis-(2- chloroethyl-) formal with alkali polysulfide.

Curing Mechanism

Silicones

Definition

Silicones are synthetic polymer containing alternate silicone and oxygen atoms as its backbone. Silicones are made from silicon (a metal obtained from silica sand) and methyl chloride (an organic compound) in a process known as the “direct process”. The Silicone sealant in the uncured state normally looks like a thick paste or cream. After curing the paste turns into an impressive rubber.

Applications

Silicone sealant are used as a form-in-place gaskets for engine & transmission applications, sealing of exterior joints, aquarium joints bonding, sealing of bath tubs, construction and glazing application, electrical potting & encapsulation, mould making, etc.

Curing Mechanism

RTV silicone systems use humidity or moisture in the air during curing and cannot be accelerated using heat (excessive heat in the curing process can be detrimental). Small amounts of by-product are also produced. The cure process will only take place if the material is open to the atmosphere and curing will be adversely affected if access to humidity is removed prior to the completion of the cure process.

Provided product types

  1. One component RTV silicone sealant
  2. Two component RTV silicone sealant

Thermal stability (constancy of properties over a wide temperature range of −50 to 250 °C) Poor tear resistance
The ability to repel water and form watertight seals Swelled by non-polar solvents
High degree of elongation Short tooling time because of skin formation
Does not support microbiological growth Primer required with some substrates (concrete)
Resistance to oxygen, ozone, and ultraviolet (UV) light. This property has led to widespread use of silicones in the construction industry (e.g. coatings, fire protection, glazing seals) and the automotive industry (external gaskets, external trim)  
Electrical insulation properties. Because silicone can be formulated to be electrically insulative or conductive, it is suitable for a wide range of electrical applications  
They have high gas permeability  
Excellent movement capability
