Optimus 3020

Slow Set Polyurea Control Joint Applications 

Product Description
Optimus 3020 Aromatic is a “Slow Set Polyurea” designed for use in interior Control Joints in warehouses and other large slab facilities.
Optimus 3020 gels in 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 Madison LS10000 application machine.  Optimus 3020 is used for installations in control joints, and can be sprayed as a membrane for other types of applications.  Optimus 3020 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.
Optimus 3020 exhibits excellent elongation of approximately 400%+ and is  resistant to moisture, chemicals and abrasive conditions.  Optimus 3020 provides “load transfer” across a standard saw cut control joint.

Moisture Vapor Reduction:  Optimus 3020 is compatible with CMW used in joints to reduce moisture vapor pressure on joint products.

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, vacuum dust. Remove any curing agent, moisture or any material that may effect 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 down 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 the part B before using. 

Application:  Use an Madison recommended 1:1 application machine or equal. Pre-condition 3020;  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 Madison 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 up.  Make the application with a slight over-pour.  Trim the over-pour from the joint area. Use stiff blades when shearing joints larger then 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 is 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 sometime rip the joint filler material.

Cold Storage Applications:  3020 is adjusted and accelerated for below zero applications, inform Madison 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, 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.
Finish:  Finished mat texture is obtained by shearing or trimming the over-pour to finished grade.
Packaging: 10 & 110 gallon kits and cartridge kits.

VOC Content:  0gms/1 or 0.0 lbs/gal

Pot Life:  Two-three minutes

This product is for use by professional applicators only.  Wear Protective Clothing

Polyurea Joint Application Using The Optimus 10000 Pump

The 10000 pump is used on a cart  because no electrical outlet is available.  A generator is added to the cart for total mobility.

Ten gallon kits of Optimus 3020 are staged in convenient locations throughout the warehouse application area.  As more product is needed it is just poured into the on-board pals.  When the job is completed the pails are discarded.

In this application two men use the cart.  In areas where the 10000 pump has access to electricity or with an added generator on the 10000 pump itself, the application only requires one person to make an installation. 

The average application linear feet per hour ranges from 800 to 1000 l.f.h.

3020 polyurea is applied using a static mixer on the end of the application gun @ ½ inch x 30 elements.  A copper tip is attached to the tip of the static mixer to keep the plastic static mixer from wearing out.  The copper tip also fits down into the joint allowing the product to fill the joint from the bottom up.  This produces less entrapped air in the pour of the product.

The overpour of product is sheared off in about an hour or so later.

Madison was one of the first companies to produce a true polyurea joint material beginning in the late 1980’s.  The product is made without catalysts and is tougher then most urethanes while allowing for penetration into the joint fill area and providing load transfer for the warehouse traffic.
