Penatron 3004

Product Description

Penatron 3004 Aromatic is a "Slow Set Polyurea” designed for use in interior Control Joints in warehouses and other large slab facilities.

Penatron 3004 gels in a few minutes, has high elongation and excellent hardness as required for control joints.  This two part polyurea is 100% solids, 100% polyurea (not a urethane), and designed to be self-leveling for joints and machine dispensed using the ASTC Little Squirt application machine.  Penatron 3004 is used for installations in control joints, and can be sprayed as a membrane for other types of applications.  Penatron 3004 is sheared or cut to finished grade in about an hour after it has set, depending on the temperature of the slab.  In some cases the product can be cut later in the day and/or may be cut the next morning.

Penatron 3004 exhibits excellent elongation of approximately 400%+ and is resistant to moisture, chemicals and abrasive conditions.  Penatron 3004 provides "load transfer” across a standard, saw-cut control joint. 

Speed & Set Time:  Gels in approximately 5 minutes, sets in 8 to 10 minutes and cures for cutting in about 60 minutes, depending on the temperature of the slab. 

Moisture Vapor Reduction:  Penatron 3004 is compatible with CMW used in joints to reduce moisture vapor pressure on joint products.  

Color:  Medium Gray

General Physical Characteristics

Preparation: Concrete must have a minimum 28-day cure prior to application.  Use a dry diamond saw, saw/abrade both sides of the joint walls, and vacuum dust. Remove any curing agent, moisture or any material that may affect bonding. Assure that the joint is properly abraded and cleaned to full depth—approximately 1.25 inches as a standard depth of fill.  For best adhesion, wash the abraded joint walls with acetone or a mix of water/alcohol applied from a tank sprayer, garden spray or similar unit.  Allow wash-down to flash off before filling.  No backer rod is used in full depth fills; use backer rod only in construction joints.  Always mix part B before using.

Application:  Use an ASTC recommended 1:1 application machine or equal. Pre-condition 3004; make sure the product is over 72°F before beginning the machine application.  Warm the product in the containers as needed to proper working temperature for this product.  Use ONLY the ASTC recommended static mixing units for this product.  Failure to use proper mixers may result in improperly mixed product and/or poor curing.  Use proper static mixers with a metal joint tracker on the end of the static mixer.  Fill the joint from the bottom of the joint.  Make the application with a slight over-pour and trim the over-pour from the joint area. Use stiff blades when shearing joints are larger than ¼ inch.

Slab Temperature and Working Temperature.
Joints should not be filled in direct sunlight or while the slab is hot.  Hot slabs have closed control and expansion joints.  The joints of a building slab should be filled when the building is enclosed.   For best results the joints should be filled at the working temperature of the building.  This is important in areas where the ambient temperature and humidity are high.  During the reduction of temperature, due to the operation of air conditions, the slab will dehydrate and shrink along with the slab’s normal shrinkage during cure.  This will open saw cut joints, construction joints and expansion joints.  If the joints are filled when the joints are hot and the slab shrinks from air conditioning (working temperature) as well as continued curing, then the joints will open and sometimes rip the joint filler material.

Cold Storage Applications:  3004 is adjusted and accelerated for below zero applications; inform ASTC when ordering this product for such applications.  Slab joints to be filled in areas where the temperature will be below zero should be filled at zero or working temperature.  Joints filled at ambient temperatures, prior to the slab being brought down to the cold working temperature, will be damaged as the joints open.

Limitations:  Do not use on wet surfaces or expose part A to moisture.  Keep 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.

Finish:  Finished mat texture is obtained by shearing or trimming the over-pour to finished grade.
