adhesive is a kind
of α-ethyl cyanoacrylate adhesive with low-viscosity and rapid
adhesion. For wood processing, general adhesion may begin to be
cured in several seconds; be able to adhere to industrial art and
educational supplies and to be used after sub-package in
advertising production, furniture repairing, plastic toy, metal
product and other industries.

the product is placed and sealed in the original package and stored
at a cool place protected from direct sunlight irradiation and from
long-term air contact (can be
refrigerated in a refrigerator for extending preservation
attentions: Dangerous and irritant gas is prevented from
eyes and skin. Otherwise, it will adhere to skins within several
seconds. In case of contact with eyes, wash eyes with plenty of
fresh water for 15 minutes and immediately seek medical assistance.
It is used in a well-ventilated place, and its contact with clothes
shall be avoided, otherwise a large amount of heat generated will
burn skin. Kept out of reach of children.
surface of adhered materials is wiped with organic solvent such as
acetone to remove grease or release agent. It shall be noted that
salt-base substances (water, alcohol, amine,
on the surface after treatment may accelerate curing of the
adhesive and acidic substance residual may slow its curing rate.
Therefore, the surface must be thoroughly
Adhesive application amount must be appropriate. Generally, thinner
adhesive layer causes higher strength; in case of more application
amount, required moisture is more and curing rate is slower;
Therefore, for compact, good-contact plat boards, adhesive
application amount of 4-5mg/cm3 is adequate.
3. If the
gap between base materials is smaller, curing rate is larger.
Therefore, it is recommended that the gap between adhered materials
shall be between 0 and 0.1mm, and Yuwang adhesion accelerator or
thickened adhesive is used for the gap over
Superimposition cant be conducted immediately after adhesive
application, and airing is conducted for 1-5s, depending on air
humidity; During adhesion, operate at the aligned position and
prevent dislocation. Otherwise, adhesion strength will be
influenced. Compression time is generally
rate is related to the temperature and humility of adhered
position. High temperature and high humility cause large curing
rate and reduced adhesion strength. The most appropriate
temperature is 20-30℃ and
most appropriate humility is 50-60%. The humility over 70% must be
avoided, otherwise whitening phenomenon will occur. Both excessive
dryness and excessive moisture will influence curing rate and
adhesion time is too long due to larger gap between base materials
or lower environmental humidity, it is feasible to use Yuwang
adhesion accelerator (add 25mg accelerator into each 20g
adhered material has better permeability, the adhesive with larger
viscosity will be more appropriate.
difficult-adhesion materials such as PE, PP, silica gel, ABS and
TPR, after their surfaces are treated with Yuwang treating agent
sprayed, their adhesion effectiveness is
gas combines with the moisture in air to cure into a white powder,
namely whitening phenomenon. If a customer proposes the restrict
requirement of whitening phenomenon, it is feasible to use products
with low whitening potential, or strengthen the air circulation or
use the corresponding promoter to reduce whitening

small area of glue, glue layer may be softened by warm water
soaking or removed with acetone.
