Technical Specification

5 Description5.1 Illmod 600 Sealing Tapes are manufacturedfrom rolls or blocks of soft polyurethane foam, cutinto sheets to the required dimensions. These areevenly impregnated with a flame-retardant syntheticresin. The adhesive layer and release paper areapplied prior to compression of the foam tobetween 15% and 18% of its fully expandedthickness. The sheets are formed into rolls and cutto the required size.

5.2 The tapes have nominal characteristics of:

colour black/anthracite

density (kgm–3)sizes to 7–12 90–110sizes from 8–15 108–132

cross-section various (see Table 1)

5.3 When fitted in a joint the tapes re-expand tofill and seal the joint. To provide a weathertightseal the optimum final compression is 20% of thefully expanded thickness.

5.4 When on the roll the adhesive layer isprotected by a silicone release paper.

5.5 Quality control checks are carried out on thefoam, impregnating mixture and on the finishedproduct.

5.6 Dimensions of the tapes are given in Table 1.

6 Delivery and site handling6.1 Tapes are supplied pre-compressed, woundinto rolls and secured by a leader tape.

6.2 Tapes are delivered in cartons (the contentsvary according to size of tapes) bearing themanufacturer’s name and size of tapes.

Design Data

7 General7.1 Illmod 600 Sealing Tapes are satisfactory foruse to provide a weathertight seal to structural andexpansion joints, and in new or existing joints instructural units of timber, plastics, masonry, metal orconcrete.

7.2 Where particularly wide joints are to be sealed,two or more tapes may be superimposed to achievethe final overall compression of between 20% and33% of the fully expanded dimension (typical tapesizes for various joint widths are given in Table 1).

7.3 Examples of indicative joint designs areshown in Figures 1 to 6.

8 Weathertightness8.1 To achieve optimum resistance to waterpenetration, the tape should be at 20% of itsfully expanded thickness. However, the tape

has a satisfactory weathertightness up to 33% of itsfully expanded thickness.

8.2 Where tapes are required to withstand ahead of water, the advice of the manufacturershould be sought.

9 Durability9.1 Samples removed from existing joints after10 years were found to have propertiescomparable with recently manufactured samples.

9.2 The first 4 mm to 5 mm of the depth of samplesshowed signs of deterioration however, this hadcaused a skin to form, helping to protect theremaining material from further degradation.

9.3 On the basis of experience gained inGermany, and data from acceleratedlaboratory tests, a useful life of at least

20 years is anticipated.

Installation

10 General10.1 Installation must be carried out inaccordance with the manufacturer’s instructions.Illmod 600 Sealing Tapes may be installed in allconditions likely to occur in practice; however,care should be taken when used at lower ambienttemperatures (see section 10.3).

10.2 Joints must be clean and free from debris, egdirt, mortar residue, likely to obstruct adhesion. Theinner surfaces of the joints to be filled should be assmooth as possible. To achieve a perfect seal inmasonry the changes in level at mortar joints mustbe as small as possible.

10.3 The tape will start to re-expand as soon as itis unwound from the roll. The rate of re-expansion istemperature dependent, and at low ambienttemperatures the rate can be increased by thegentle application of heat. At high temperatures thetapes should be stored in a cool environment priorto use (see Table 2).

(1) At temperatures below 0°C re-expansion will be slow.

11 Practices11.1 The dimensions of the joint to be filledgovern the size of tape used, but the depth of thejoint must not be less than the width of the tape.For particularly wide joints two or more tapesmay be superimposed.

11.2 When using the tapes to seal betweenprefabricated units during construction, the sealmust be bonded to the unit already in position.The adjoining unit can then be fitted.

11.3 Joints should be designed and the tapespositioned so that differential movement betweenpanels does not tend to force the product out ofthe joint.

11.4 The length of the joint to be sealed must bemeasured and an overlap of 10 mm per metrerun allowed when the tape is cut to the requiredlength. The silicone release paper must beremoved and the tape positioned in the joint,starting at the end and aligned with a shortstraight edge set back from the front face of thejoint (see Figure 7).

Technical Investigations

The following is a summary of the technicalinvestigations carried out on Illmod 600 SealingTapes.

12 Tests12.1 Tests were carried out in Germany by theHessian Agricultural Experimental Establishment inDarmstadt, MPA Nordrhein Westfalen, and theInstitute of Building Materials Science andMaterials Testing at Hanover University. The resultsof the tests, which are typical values for thematerial, are summarised in Tables 3 and 4.

12.2 Samples taken from existing sites 10 yearsafter installation were examined and subjected tomany of the tests listed in Tables 3 to 5. Thesamples were found to have properties comparablewith new material.

When installing Illmod in an existing joint, usea wedge to temporarily secure one end and ifnecessary, wet the adhesive face to facilitateinsertion of the tape.

At joint intersection run Illmod fully in onedirection and butt with a small excess on bothsides.

When sealing long joints allow a small excesslength of Illmod at each cut.

When installing windows allow excess by forminga wave on each of the four butt jointed strips, andpress down to ensure good sealing on all corners.
