Description:

Comens Secubond PT905 is a two-part methacrylate adhesive designed for structural bonding of metals without primers. PT905 can bond most of the metal except copper without primers in the case of simple surface treatment. The product can also be used to bond common engineering plastics , especially suitable for bonding composite materials. PT905 can be used on a vertical plane with good thixotropy.


Characteristics:
1.100% Curing
2.Surface does not need to be treated strictly
3.Working time 4-6min
4.Fast curing
5.Widely used in various metals and engineering plastics
6.Excellent Fatigue Resistance
7.High Strength
Uses:
Used to bond the following materials

metals: aluminum, cold rolled steel, magnesium alloy, stainless steel

Engineering Plastics: PC/ABS, ABS, acrylic resin, polycarbonate, PVC

Composite materials: epoxy, unsaturated polyester, vinyl ester and polyurethane.


Technical Data Sheet:

Note: the following information and data are typical values under standard conditions, not as basis for product acceptance. If the test environment is not explicitly mentioned in the following tests, the test environment is unified to a temperature of 24 ± 2ºC and a humidity of 50 ± 5% RH.

Note:
1. Working Time: It refers to the time when the PT905 is mixed from the part A and B to the time when the adhesive is no longer useable on approximate 5mm beads. Times presented were tested at 24ºC.
2.Fixture Time: Varies with ambient temperature, bondline gap thickness, and nature of substrates. Typically at 24ºC, PT905 with 0.75mm gap reaches 3MPa in 20 minutes, and 7MPa in 25 minutes on Al 6061 . Substrate, temperature and gap may also affect fixture time(GBT 7124-2008).
Storage and Shelf Life:
Comens Secubond PT905 is packaged in a 490 mL side-by-side double tube. The recommended storage temperature is 8-25ºCand the storage period is 12 months. Storage at 12ºC helps to extend the shelf life of the product. Long-term exposure to temperatures above 25 ºC will shorten the shelf life of the product.The initiator component decomposes rapidly above 35ºC to destroy product reactivity. Do not expose the product to high temperature storage. Recommended storage environment: ventilated, dry and dark.
Application Note:

Although the Comens Secubond PT905 does not require special surface treatments and can even be bonded with oil, in order to achieve the desired bonding effect, it is recommended to clean the surface of the adherent substrate with dust and oil in the following manner:

metal:Wipe once with acetone,Wipe once with alcohol

Plastic substrate:Wipe twice with alcohol
Compsite materials: Surface grinding and clean the surface with dry cloth

It is recommended to use the 490mL 10:1 manual/pneumatic glue gun (Mixpac/NSJ)and mixing tube recommended by our company for sizing work.
