Penatron 3050 is an aromatic "Slow Set Polyurea” designed for use in interior vertical applications where a tough but flexible caulking is required. It is designed with vertical hold and sets in about 3-5 minutes. The product has a high Shore A hardness, 90-95 and elongation of approximately 200%+.
Penatron 3050 is a 1:1 system and can be used via a duplex cartridge or the ASTC LS 1:1 electric pump. Mixing is accomplished using a ½ inch x 30 inch element static mixer. This two-part polyurea is 100% solids, 100% polyurea. It may be immediately tooled or smoothed after placement or sheared to finished surface grade after the product has set firm enough to be cut.
Cold Temperature Applications: Heat the product overnight in the containers to 75°F-90°F and keep the product and equipment warm during the application.
Priming: Large opening, voids or control joints should be primed using Penprime 7001 approximately 1 to 2 hours before the application of the 3050.
Moisture Vapor Reduction: Penatron 3050 is compatible with CMW used in joints to reduce moisture vapor pressure on joint products.

Advantages
USES AND AREAS
Preparation: Concrete must have a minimum 28-day cure prior to application. Use a dry diamond saw, and saw/abrade both sides of the joint walls. Assure that the joint is properly abraded and cleaned to full application depth. Backer rod is used in deep fills with the backer rod at least twice the depth of the width of the area to be caulked. Remove any curing agent, form release materials, oils, wax, moisture or any material that may affect bonding. Clean with dry diamond saw, vacuum and wash to remove dust from the walls of the joint.
Application: Use an ASTC recommended 1:1 application machine or equal or pre-packaged duplex cartridges from ASTC. Pre-condition 3050; make sure the product is 72°F+/-5°F before beginning the machine application. Warm the product in the containers as needed to proper working temperature for this product.
Caulking: Fill the area to be caulked from the bottom up. Make the application with a slight over-pour. Trim the over-pour from the area when the product has set enough to allow cutting. Use a very sharp razor cutter to make the cut. Use stiff blades when shearing joints larger than ¼ inch. The product may be tooled in the fill area as needed.
Coving: When used at intersections of floors and walls to form a small cove, it is best to use a rubber cove tool. Immediately use the coving tool as the product is applied; this usually takes two people.
Limitations: Do not use on wet surfaces or expose part A to moisture. Not designed for Expansion Joints or high movement joints; use only in areas where a hard/flexible chemical resistant material is needed. Keep packaged product out of direct sunlight and store ten gallon kits on wood pallets at room temperature. Warm product kits on pallets before using. Protect from cold conditions when using this product in cold storage.
Shelf Life: 1 year; store between 40°F and 100°F.
Packaging: 21 ounce and 54 ounce cartridges (requires lead time), 10 gallon & 110 gallon kits.
VOC Content: 0gms/1 or 0.0 lbs/gal
