亨斯迈爱牢达AV119 TDS

近日了解到亨斯迈旗下有一款爱牢达AV119产品，主要是单组分热固化环氧胶粘剂，产品TDS我大概看了一下，应该与目前的红胶体系有些类似，但是有两个比较特殊的地方，一个是粘接强度非常大，另外一个是具有一定的韧性，可以承受高频的震荡冲击。据了解市面的价格好像是五六百块一公斤，而且这个产品也是按公斤来销售的，估计用量也不小。有空让公司研发部门分析一下此款产品，顺便也去了解一下此类产品的应用点。闲话少说，先贴上TDS资料，需要看原版的请下载附件查看！：

ARALDITE® AV 119
EPOXY ADHESIVE PASTE
DESCRIPTION: Araldite AV 119 epoxy adhesive is a one-component, multi-purpose paste that
is thixotropic and is designed for heat curing at temperatures from 248°F to
356°F (120°C to 180°C). The adhesive will fill gaps to 0.12 in. (3mm). The
tough, high-strength adhesive is well suited for metal bonding and joining
materials including ceramics, glass, rubber and temperature-resistant plastics.
APPLICATIONS: Metal- to-metal bonding.
ADVANTAGES: • Good heat resistance to 248°F (120°C)
• Good peel strength
• Good chemical resistance

PROCESSING Pretreatment
The strength and durability of a bonded joint are dependant on proper treatment
of the surfaces to be bonded. At a minimum, joint surfaces should be cleaned
with a good degreasing agent such as acetone or other proprietary degreasing
agents in order to remove all traces of oil, grease and dirt.
Low grade alcohol, gasoline or paint thinners should never be used.
The strongest and most durable joints are obtained by either mechanically
abrading or chemically etching (“pickling”) the degreased surfaces. Abrading
should be followed by a second degreasing treatment
Adhesive Application
The resin/hardener mix is applied with a spatula, to the pretreated and dry joint
surfaces.
A layer of adhesive 0.002 to 0.004 in. (0.05 to 0.10mm thick) will normally impart
the greatest lap shear strength to the joint.
The joint components should be assembled and clamped as soon as the
adhesive has been applied. An even contact pressure throughout the joint area
will ensure optimum cure.
Mechanical processing
Specialist firms have developed metering, mixing and spreading equipment that
enables the bulk processing of adhesive.
Huntsman Advanced Materials will be pleased to advise customers on the choice
of equipment for their particular needs.
Equipment maintenance
All tools should be cleaned with hot water and soap before adhesives residues
have had time to cure. The removal of cured residues is a difficult and timeconsuming
operation.
If solvents such as acetone are used for cleaning, operators should take the
appropriate safety precautions and, in addition, avoid skin and eye contact.

Note: Temperatures below 248°F (120°C) will not give adequate cure even when
cure time is prolonged.
Cure temperatures above 302°F (150°C) should be avoided when joining
materials with different coefficients of linear thermal expansion because stresses
will be set up in the bond line upon cooling. This effect is particularly marked
where the bond surfaces are large.
Typical cured
properties
Unless otherwise stated, the figures given below were determined by testing
standard specimens made by lap-jointing 6.6 x 1.0 x 0.06 in.(170 x 25 x 1.5mm)
strips of aluminum alloy. The joint area was 0.5 x 1.0 in. (12.5 x 25mm) in each
case.
The figures were determined with typical production batches using standard
testing methods. They are provided solely as technical information and do not
constitute a product specification.
