| AH-509A Transparent all-purpose adhesive
AH-509A Transparent all-purpose adhesive is a hi-tech product developed
by our company. It is made of many kinds of senior Fine Chemical Raw
Materials with updated formulation and improved production technology.
It has the features such as wide application, excellent performance
and convenient usage.
[Appearance] Adhesive in
group A is grey thickened liquid, while that in group B is light yellow
[ Features] It is a double-troop curing adhesive
with its room temperature between 20℃ and 30℃. It can be heated and
cured, adjusted into many different colors. It has such features as
high splicing strength, good sealability, and water resistance, boiling
water resistance, oil resistance, insolation resistance, dilute acid
resistance and alkali resistance. The service temperature is 60～120℃
while its transient service temperature is 150-220℃. It is also insulated.
[Purpose] it can be used to bond things such as china,
stone, glass, metal, concrete, bamboo and wood articles, vulcanized
rubber, leather, some plastic and woven cloth. It can be used between
materials of the same or different kinds, and used to mend the crannies,
repair the defects, seal the containers and Insulation Encapsulating.
It is widely used in many fields such as handicraft production, electronics,
repair and maintenance, construction and decoration, instruments,
transportation equipment, and war and civil industries.
(1) Surface treatment: Clean and dry the surface of the thing which
needs bonding or mending. Remove its oil stain, iron mould, dust,
etc. It is normal to use solvents such as acetone and absolute ethyl
alcohol or cleaning agent to clean the surface or treat it with mechanical
methods such as polishing and sandblasting. However, chemical treatment
can increase its bonding strength, especially for some plastic which
is difficult to bond.
(2) Adhesive preparation: Group A: Group B = 2 : 1. Mix the adhesives
in Group A and Group B well and completely. The adhesive should be
used up within 30 minutes after being mixed. Adhesive preparation
can be done in the plate or board made of metal, glass or plastic
as well as special container for mixing. But the tools and containers
for adhesive preparation must be kept dry and clean.
(3) Adhesive spreading: the adhesive which has been prepared can be
spread with tools such as scraper, small bar or writing brush onto
the surface of the treated article which needs bonding or mending,
or spread with double-troop auto adhesive-spreading machine. The surface
of two articles should be painted with average and proper adhesive.
(4) Bonding: Join properly the articles which have been painted with
adhesive.In the initial stage of bonding, you can fix the articles
by clipping with tools, tying with tapes or orienting with instantaneous
adhesive and avoid the adhesive flowing in the same time. If the adhesive
is used to patch or mend the articles, you should stick fiber cloth
and metal pieces or twine the cotton thread and iron wire after the
surface of articles is painted with adhesive.
(5) Curing: The articles are cured initially within 6 hours after
bonding. They can Basic curing in 24 hours. They enjoy high strength
7 days later. Curing by heating can reduce the curing time with better
[ Bonding strength] (Room temperature): The articles
such as glass, ceramics, concrete and bamboo or wood ware will be
pulled without adhesive failure. Cutting strength: 45# steel ≥18.2MPa,
Aluminum alloy ≥16.2MPa, and tensile strength≥27.8MPa.
