BD4264 alkali resistant anti-stripping prime coat
Product usage:
This product is a high performance alkali-resistant polymer material made of modified high strength alkali resistant resin and modified curing agent. It can withstand a variety of alkali solutions, has good alkali cathodic
disbondment resistance, and has good toughness and impact resistance. , High bonding strength with metal substrates, commonly used to increase the adhesion between wear-resistant coatings and metal substrates and
improve the performance of wear-resistant coatings and cathodic disbondment resistance.

How to use:
1. Surface treatment: clear up the pending-repair parts,expose the fresh metal substrate,do the roughing treatment for the fresh substrate,the treated surface should be a clean,dry, rough and fresh surface.
2. Preparation: accurately weigh out the right amount of A and B components according to the proportion required by product labeling,and stir them thoroughly to mix them evenly.The mixed prepared material should be
used up within the specified operating time limit (the material after becoming sticky and hard can’t be used again)
3. Coating:make the mixed prepared materials be coating on pending repair parts and press it compacted,make it infiltrate fully with the substrates,the adhesive layer needn’t be too thick,it is advisable to 0.2 to 0.5mm.
4. Using the wear resistant coating:Apply wear resistant coating before BD4264 alkali resistant prime coat is not cured.
5.Curing: After the wear resistant layer is finished, it is cured under the same conditions as the wear resistant layer.
Special version:
1. All parameter data marked in this document are obtained by our company’s laboratory or commissioned by a third-party test. We strive to make these parameter data accurate and reliable. However, due to the complexity
and diversity of actual working conditions, we specifically declare: It is only for reference and reference for users, not as a basis for purchase or claim settlement. At the same time, it is recommended that the user simulate the
real working environment for pre-test before use, and use the test results to judge whether the product is suitable for actual working conditions.
2. The method of use in this document is only a general guideline plan, please determine the appropriate construction plan according to the actual working conditions on site before the formal construction
3.When the construction environment temperature is below 25¡æ,the curing time will prolong,if you want to expedite the curing speed, should take proper heating measure
4.When the construction environment temperature is more than 25¡æ or the mixing quantity is too large,the curing speed after mixing will expedite,should properly shorten the application time of coating after mixing.
Construction protective measures:
1.Wear the protective masks,wear the protective glasses and rubber gloves
2.Need washing hands with soap before eating,drinking or smoking.
3.The health hazard after touching: a few people will have skin allergy phenomenon,see a doctor in time and avoid touching with this product again.should wipe it with ethyl acetate when the sizing material paste on the skin
by careless,then wash it with clear water.Should wash it with clear water immediately and see a doctor when splashing into the eyes by careless.
Warm Prompt:
Residual adhesive solution cured products are non-toxic harmless organic solid,but maybe it will produce poisonous gas when burning,non-professional personnel can not do combustion disposal,should be sent to garbage power
plant or garbage burning place treatment.
